CAR-.COUPLING.

SPECIFICATION forming part of Letters Patent No. 464,572, dated December8, 1891.

Application led July l5, 1891.v

To all whom t may concern.-

Beitknown that I, GEORGE D. LEWIS, a citizen of the United States,residing at Port Allegheny, in the county of McKean and State ofPennsylvania, have invented a new and useful Oar-Coupling, of which thefollowing is a specification.

This invention relates to car-couplings of that class known as twin-jaw,and the object thereof is to produce certain improvements in devices ofthis character.

To this end the invention consists in the construction hereinafter morefully described and claimed, and as illustrated on the sheet ofdrawings, wherein- Figure 1 is a perspective view of the end of av carwith my improved coupling attached taken slightly from the under side.Fig. 2 is a plan View of two draw-heads coupled or connected, the uppersides thereof being removed to more clearly illustrate the interiorconstruction. Fig. 3 is an enlarged perspective detail of one wing andits operating-lever.v

Referring to the said drawings, the letter B designates the body ofthecar, beneath which is secured the draw-bar D, whose front end ordraw-head is U-shaped in plan and connected at its bend with the drawbar. The latter stands slightly out of the transverse center of the car,so as to throw one of the arms A of the draw-head nearly in the center,while the other arm A is quite remote therefrom. In the front end of thearm A is the usual opening O for the reception of an ordinarycoupling-link when this. draw-head is to be connected with one usingsuch link. The arm A is hinged, as at H, to the body of the draw-head,so that it can be turned outwardly, as seen in dotted lines in Fig. 2,and a hook h, pivoted to the top of the body, en-

' gages a staple or eye t' in the top of the arm which is hollow andthen turn to the rear,

whereby the wings are prevented from movving outwardly too far.

` L is a lever centrally pivoted within the body and pivotally connectedat its front end with one of the feet F, and S is a spring operating onthis lever in a direction to move the Wing normally out of the recess R.In the arrn A there are two such levers mounted on a single pivot like apair of shears, and of course moving oppositely in order to draw thewings simultaneously inward.

C arev chains leading from the levers inwardly, and one of these chainsO', which leads from the lever that operates the wing on the outer faceof the arm A passes around a pulley P, as shown. The meeting ends oftheA chains are connected, pass upwardly through a hole in the top ofthe draw-head, and lead to any suitable devices (not shown) foruncoupling. W'ith this construction of devices it will be obvious thatwhen the two draw-heads come together, as seen in Fig. 2, the wings willspring outwardly and engage each other; and that when it is desired touncouple the cars a pull upon the chain C will move all the levers Lsimultaneously, compress their springs S, and draw the several wings WVinto the recesses R, whereby the other draw-head would be allowed topullout. The parts are of any desired size and material and considerabledeparture in the specific details may be made without losing sight of myinvention. The height or vertical thickness of the draw-head maybeconsiderable,

and hence cars whose draw-heads stand at- IOO arms of said draw-head,L-shaped feet on said Wings passing into the draw-head, pivoted andspring-actuated levers bearing said feet and Wings normally outward, andchainsleading from the rear ends of said levers over suitably-locatedpulleys to a common point, and thence out the top of the draw-head, asand for the purpose set forth.

2. In a car-coupling, the combination, with the draw-bar, the U-shapeddraw-head secured at its bend to the front end thereof, one

of the arms being rigid with and the other connected by a hinge to saidbody, and a catch for holding this arm normally rigid, ofspring-actuated Wings on both faces of the 15 Vrigid arm, a single Wingon the inner face of
